    Hi Pix
    Thanks for your answer.
    The vendor is Huawei.
    We have a big number of “Number of Downlink EGPRS TBF Abnormal Releases due to Other Cause” and “Number of Uplink EGPRS TBF Abnormal Releases due to Other Cause”.

    In BH, an average of
    UL TBF estab fail: 79%%
    DL TBF estab fail: 32%%
    UL TBF DROP: 9%
    DL TBF DROP: 23%

    We increase the timer N3101 for improving UL TBF drop and N3105 for DL TBF drop if it helps someone. Now the TBF drop is less than 2%
